在Eclipse ADT更新后的错误

在我的日食最后一个版本的ADT是API 16，所以我更新ADT（Eclipse的>帮助 - >安装新的软件 - >与工作：ADT），然后出现多个错误！

Last version of ADT in my eclipse was API 16, so I updated ADT (eclipse->Help->Install new software->Work with: ADT ) and then multiple errors occurred!!!

我甚至不能开放的Andr​​oid SDK管理器！

I can not even open Android SDK Manager !

有一些截图来自错误：

我怎样才能回滚？！

P.S：之前更新ADT我试图通过复制一个jar文件中增加的SQLiteManager插件为日蚀/的dropins /文件夹，但是Eclipse并没有再运行。所以我删除了jar文件，黯然失色成功午饭！

P.s : Before Updating ADT I tried to add "SQLiteManager" PLugin by copying a jar file into "eclipse/dropins/" folder, but eclipse did not run anymore. So I removed the jar file and eclipsed lunched successfully!
